In this study subjects will be assigned by chance to either the active product group or the placebo group. Subjects will take the product for three weeks. Then there will be a two week wash out period followed by subjects being crossed over to the other group for a three week period. Subjects, assessors, and health providers will be masked as to who is in the active product group and who is in the placebo group. Subjects will meet with the primary investigator three times during the study, will fill out very short questions once a week, and receive phone calls once a week from study personnel.
